Clients and relays haven't used them since early 0.2.0.x. The only
remaining use by authorities learning about new relays ahead of scedule;
see proposal 147 for what we intend to do about that.
We're leaving in an option (FetchV2Networkstatus) to manually fetch v2
networkstatuses, because apparently dnsel and maybe bwauth want them.
This fixes bug 3022.
If we're picking a random directory node, never pick an excluded one.
But if we've chosen a specific one (or all), allow it unless strictnodes
is set (in which case warn so the user knows it's their fault).
When warning that we won't connect to a strictly excluded node,
log what it was we were trying to do at that node.
When ExcludeNodes is set but StrictNodes is not set, we only use
non-excluded nodes if we can, but fall back to using excluded nodes
if none of those nodes is usable.
We fixed bug 539 (where directories would say "503" but send data
anyway) back in 0.2.0.16-alpha/0.1.2.19. Because most directory
versions were affected, we added workaround to make sure that we
examined the contents of 503-replies to make sure there wasn't any
data for them to find. But now that such routers are nonexistent,
we can remove this code. (Even if somebody fired up an 0.1.2.19
directory cache today, it would still be fine to ignore data in its
erroneous 503 replies.)
We had a spelling discrepancy between the manpage and the source code
for some option. Resolve these in favor of the manpage, because it
makes more sense (for example, HTTP should be capitalized).
- Move checks for extra_info to callers
- Change argument name from failed to descs
- Use strlen("fp/") instead of a magic number
- I passed on the suggestion to rename functions from *_failed() to
*_handle_failure(). There are a lot of these so for now just follow
the house style.
It's normal when bootstrapping to have a lot of different certs
missing, so we don't want missing certs to make us warn... unless
the certs we're missing are ones that we've tried to fetch a couple
of times and failed at.
May fix bug 1145.
requests to authorities fail due to a network error.
Bug#1138
"When a Tor client starts up using a bridge, and UpdateBridgesFromAuthority
is set, Tor will go to the authority first and look up the bridge by
fingerprint. If the bridge authority is filtered, Tor will never notice that
the bridge authority lookup failed. So it will never fall back."
Add connection_dir_bridge_routerdesc_failed(), a function for unpacking
the bridge information from a failed request, and ensure
connection_dir_request_failed() calls it if the failed request
was for a bridge descriptor.
Test:
1. for ip in `grep -iR 'router ' cached-descriptors|cut -d ' ' -f 3`;
do sudo iptables -A OUTPUT -p tcp -d $ip -j DROP; done
2. remove all files from user tor directory
3. Put the following in torrc:
UseBridges 1
UpdateBridgesFromAuthority 1
Bridge 85.108.88.19:443 7E1B28DB47C175392A0E8E4A287C7CB8686575B7
4. Launch tor - it should fall back to downloading descriptors
directly from the bridge.
Initial patch reviewed and corrected by mingw-san.
This was freaking out some relay operators without good reason, as
it is nothing the relay operator can do anything about anyways.
Quieting this warning suggested by rieo.
Before it would prepend your requested entrynodes to your list of guard
nodes, but feel free to use others after that. Now it chooses only
from your EntryNodes if any of those are available, and only falls back
to others if a) they're all down and b) StrictNodes is not set.
Also, now we refresh your entry guards from EntryNode at each consensus
fetch (rather than just at startup and then they slowly rot as the
network changes).
The goal here is to make users less likely to set StrictNodes, since
it's doing closer to what they expect it should be doing.
The HSAuthorityRecordStats option was used to track statistics of overall
hidden service usage on the version 0 hidden service authorities. With the
version 2 hidden service directories being deployed and version 0
descriptors being phased out, these statistics are not as useful anymore.
Goodbye, you fine piece of software; my first major code contribution to
Tor.
In connection_dir_client_reached_eof, we make sure that we either
return when we get an http status code of 503 or handle the problem
and set it to 200. Later we check if the status code is 503. Remove
that check.
